Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.A-tier. Bet on this one — the Sparkpage format is genuinely new.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
